ABSTRACT:
The present invention relates in general to mobile telecommunications terminals, and more particularly to the facilities offered by such terminals for accessing telecommunications services.
BACKGROUND OF THE INVENTION
As an example of such facilities, mention can be made of: the option of storing phone book type data, facilitating access both to “basic” services and to “value-added” operator services (such as interactive services, in particular), or indeed to perform operations on “supplementary” services (for example call forwarding, barring outgoing calls, etc. . . . ), or indeed, for mobile telecommunications networks that provide not only a telephony service but also a service for transmitting short alphanumeric messages, the option of storing short alphanumeric messages to be transmitted, or as received, by said terminals.
It is known to store data related in this way to such facilities in the terminal itself, or for greater flexibility, in an element referred to as a “subscriber identity module” which, in practice, is in the form of a smart card designed to be inserted in the terminal to enable it to be used, said card also being referred to as an “SIM” card (for “subscriber identity module”) in the mobile telecommunications system known under the name GSM (for “Global System for Mobile communications”).
As laid down in GSM Recommendation 11.11, the data relating in this way to such facilities, together with the data relating to subscriber identity, is stored in predetermined memory zones of the card, in such a manner as to ensure that the card is compatible with the various types of GSM terminal that might receive it. It is thus possible to take advantage of said facilities from any terminal capable of receiving such a card.
OBJECTS AND SUMMARY OF THE INVENTION
A particular object of the present invention is to increase the quality of service related in this way to such facilities, but to allow such an improved quality of service to be obtained only from certain kinds of terminal, thus making them recognizable by the quality of service they provide.
The invention thus consists in a subscriber identity module for a mobile telecommunications terminal, said module including means for storing “basic” data relating to facilities offered to the user for accessing telecommunications services, said data being stored in a predefined memory zone in order to ensure compatibility between the module and the various types of mobile terminal that are suitable for receiving such a module, and said module essentially further including means for storing associated complementary data, relating to complementary facilities, and for storing said data in another predefined memory zone so as to provide compatibility between the module and certain terminals only.
The invention also provides a mobile telecommunications terminal designed to be fitted with such a module, the terminal including means for reading basic data stored in such a module, and means for making use of basic data read in this way, and said terminal essentially further including means that make it possible, when reading basic data, to control subsequent reading of associated complementary data, and to make use of the complementary data read in this way.
The invention also provides a mobile telecommunications terminal for co-operating with a subscriber identity module itself including means for storing “basic” data relating to facilities offered to the user for accessing telecommunications services, the terminal including means for reading such basic data stored in such a module, and for making use of the basic data read in this way, and said terminal essentially further including means for storing associated complementary data relating to complementary facilities, and means making it possible, in the event of reading basic data in said module, to control subsequent reading of associated complementary data in said terminal, and to make use of the complementary data read in this way.
